Glaucoma secondary to eye trauma, left eye, moderate stage

This code signifies a form of glaucoma that develops as a direct consequence of an injury to the left eye. It indicates that the intraocular pressure elevation and optic nerve damage are secondary to a traumatic event, and the disease has progressed to a moderate stage.

Use this code when documentation clearly links the patient's glaucoma in the left eye to a prior eye trauma. This typically applies to cases where the trauma led to structural changes or inflammation that subsequently caused increased intraocular pressure. Supporting documentation should include a history of eye injury and ophthalmological findings consistent with moderate-stage glaucoma.

• Always code the underlying eye trauma first, if still active, or a history of trauma code if the injury is resolved.
• Ensure the documentation specifies "left eye" and "moderate stage" to support this specific code.
• Differentiate from other secondary glaucomas (e.g., inflammatory, drug-induced) by confirming a direct causal link to trauma.
